DEFINITION

Classification: 426/231

(under the class definition) Processes where a condition in preparing subject matter of this class is sensed by other than by subjective means.

(1) Note. Subjective evaluation is proper for this subclass if the matter evaluated is indirectly determined, that is for example if a measurement is made inanimately and then read or sensed by a human being e.g., reading a spectrophotometer, etc..

(2) Note. Treating a material to a certain condition without a defined inanimate measurement, test, inspection, or control, e.g., temperature, PH, etc.., is not proper subject matter for this subclass and classification of such a process will be accorded on some other basis.
